Section titled “Sources of truth: Bitcoin Stamps”| Question | Answered by |
|---|---|
| What is for sale, and at what price | StampDEX Counterparty dispenser order book |
| Who owns it | StampDEX/Counterparty indexer-backed compose validation plus wallet PSBT signatures |

| Primary index | StampDEX and Stampchain |
| Fallback sources | OpenStamp for reference metadata |
| Freshness policy | Universe does not enforce a StampDEX-versus-chain lag threshold. |
| Confirmation policy | Confirmation policy is delegated to StampDEX/Counterparty. |
| Reorg policy | Universe relies on StampDEX/Counterparty state and has no local rollback worker. |
Sources of truth: SRC-20
Section titled “Sources of truth: SRC-20”| Question | Answered by |
|---|---|
| What is for sale, and at what price | StampDEX SRC-20 order book |
| Who owns it | StampDEX one-time action challenge, seller listing PSBT, and indexed SRC-20 collateral checks |
| Whether a trade completed | StampDEX fill/confirm endpoints plus wallet Bitcoin broadcast |
| Protocol state | StampDEX |
| Primary index | StampDEX |
| Fallback sources | Stampchain activity; OpenStamp mint/deploy reference data |
| Freshness policy | Universe does not enforce a StampDEX-versus-chain lag threshold. |
| Confirmation policy | Confirmation policy is delegated to the StampDEX fill workflow. |
| Reorg policy | Universe retains broadcast receipts but delegates chain reconciliation to StampDEX. |
Enforcement fields
Section titled “Enforcement fields”| Field | Bitcoin Stamps | SRC-20 |
|---|---|---|
| Freshness enforced by Universe | No | No |
| Maximum lag in blocks | Not set | Not set |
| Maximum observation age | Not set | Not set |
| Listing minimum confirmations | Not set at this layer | Not set at this layer |
| Settlement minimum confirmations | Not set at this layer | Not set at this layer |
| Automatic reorg reconciliation | No | No |
Not set at this layer does not mean zero. It means the number is decided by StampDEX and Counterparty rather than by the Universe registry. StampDEX itself settles at two confirmations; see Settlement lifecycle.
